Application filed May 1a, 1925. serial as. 30,679.

My invention relates to a door brace. In general. the object of my invention is to provide a brace for a door ,which shall be positive acting, economical of space, both in operative and inoperative positions; and simple to manufacture.

My invention willbe best understood from the following detailed description taken with the annexed drawing, in which:

Figure 1 is a View in side elevation of a preferred form;

Figure 2 is a view similar to Figure 1 but seen from the front;

Figure is a detail view ofthe top portion of the brace; p,

Figure 4- is an enlarged view partly in section of the lower end of the brace;

Figure 5 is a view in section taken along line 55 of Figure 1; and Q Figure 8 shows an alternative means for attaching the brace to the door.

In the above drawings 10 denotes the bracing rod which is attached, to the door 11 preferably by means of a universal joint consisting of a flanged cylindrical member 12 rotatable in a socket member 13 which is secured to the door by means of wood screws lat. Cylindrical member 12 is pivoted to rod 10 by means of a hinge member 15 secured to the top oii'rod 10. f

For insuring a more positive looking action of the brace I have provided a special means consisti g of a wedge member 16 whichis slidably held to the bottom of rod 10, suitably by means ofa pair of screws 17 in rod 10, the portions of the screws projecting therefrom engaging a slot .18 in the wedge 18. Slot 17 communicates with the enlarged slot 19 to accommodate the heads of screws 17. Preferably a bearing surface is provided for t e heads of screws 17, in the form of a metal lining 20 secured to (the bottom of slot 19 in order to protectfrom injury the material of which the "wedge is made.

I also preferably provide pegs .20 of resilient material, as "for example rubber, be tween the floor and the wedge.

In use, the door having been closed, the rod 10 dropped into position with wedge 18 outwardly protruding slightly as shownlines of Figure 2.

in Figure 1. The wedge is then driven home by engaging same with the foot whereupon the rod 10 is j ammedseourely between the wedge 16 and the door 11. In all the prior devices with which I am "familiar, the bracing rod does not jam until after the door has been opened an appreciable amount. In

my improved device, on the other hand, the brace 1s ammed between the door and the floor when, the door is in the closed position thereby preventing it from being opened even a slight amount. Moreover, by means of this construction the angle of the rod 10 with the door 11.. may be relatively'small. This enables the rod to act as a column because the reaction on the rod is very'nearl coincident with the axis thereof. In addb' Asshown, I have provided a collar conslstmg of separable sections 21, 21 "which engage the neck 22 of the door knob 23. Preferably I line the collar sections 21 and 21 by means of a resilient material of suitable com'position such as rubber whereby PATENT errie s.

injury to the doorknob is prevented. This 1 construction provides lateral motion. of the brace similar tothe-oylinder and. socket arrangementotFigure 1. 5

' It. will be apparent from the foregoing that I have provided a simpleyet effective device for the purpose described and which may be cheaply and easily manufactured. It will also be understood that various changes may be made'in the illustrated-device without departing 'from the spiritof the invention or the scope of the claims.
